Koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Rotschwanz-Schattenkolibri

A large hermit hummingbird of humid lowland and foothill forests from Central America through the Amazon basin, rufous-breasted hermits have cinnamon-rufous breast and underpart plumage contrasting with bronzy-green upper parts and a long curved bill. Males gather at leks — communal singing assemblies — where they perform vocal displays to attract females. They follow trap-line routes through dense forest understory. Important pollinators of large Heliconia flowers in tropical rainforest.
